Abstract

Cleaning gases comprises passing the gas through a bulk material bed using a bulk material feeding container (12) with a charge opening and a closable discharge opening (14). Cleaning gases comprises passing the gas through a bulk material bed using a bulk material feeding container (12) with a charge opening and a closable discharge opening (14). The feeding container is charged with bulk material in at least one charging position and is moved via a first bulk material bed and its discharge opening released so that the bulk material is released until the bulk material bed reaches its theoretical height of bulk material. Release of bulk material and subsequent further processing for further beds is repeated. After complete bulk material partial exchange, especially for more beds, the feeding container is moved back to the charging position. An Independent claim is also included for a treatment apparatus for carrying out the cleaning process.

Description

The invention relates to a method for treatment, in particular especially for cleaning fluids according to the preambles of Claims 1 and 18, and a charging device and Gas treatment plant for performing the method according to the preambles of claims 8 and 10.

In systems for treating large amounts of gas, such as. B. occur as exhaust gas in combustion processes, in particular for removing environmentally harmful components such as jam ben, dioxins, sulfur and heavy metals, on a bulk Well, a major problem is the large area the bulk goods sometimes also referred to as "filters" layer. Namely, it is desirable to have the flow resistance by keeping the bulk layer low and at the same time a high quality of treatment across the entire filter cross ensure permanent cut. In order to achieve this the bulk material if it is countercurrent to the material to be treated Fluid, so particularly effective, should be used in Ways of exchanging bulk parts consistently evenly  at the bottom of the bulk material layer, the inflow floor and equally evenly fresh bulk goods over the bed top distributed area. This is a big problem technically solved by so-called moving bed reactors as described in WO 88/08746, WO 91/12069 and EP 0 472 565 have been described.

In these known methods, devices and systems the bulk material is transferred to the bulk material storage bunker and bulk material well-distributed soils that are immediately above any bulk material beds are arranged, fed. The bulk material discharge opening Openings of the bulk material distribution floors are permanently open NEN pipe mouths formed, below which each one Bulk cone forms. Because these mouth openings are over the bed cross-section is evenly distributed Bulk bed surface of a plurality of such bulk well cone formed. The one between the bulk bed surface and the bulk goods distribution floor inevitably remaining Cavity of each bed serves as a gas collection space that has a lockable opening in the side wall of the bulk material bed-holding container (reactor) with a gas collection or discharge channel into which the combined exhaust gas flows all beds open, is connected. Through the permanent open mouth or discharge openings of the bulk goods ver Partial soil can also be treated fluid in the bulk material penetrate storage bunker. Therefore, special precautions are required to make sure that the refill openings of the bulk goods bunkers are always sufficiently sealed and that in treated gases entering the storage bunkers in the fore advice bunkers no undesirable reactions such. B. by oxygen-containing creeping flow, so-called hot spots, cause.

Another problem with these known fluid treatment plants is that the type of distribution of the Bulk goods on the reactor beds and / or the discharge  Bulk goods a relatively rigid definition on a passing agreed procedure for fluid treatment to have.

Proceeding from this, the invention is based on the object Process, charging device and gas treatment to propose system by which the leakage risk for treated gas reduced above the bulk bed becomes.

Since the known moving bed reactor plants in comparison there is a large system height for the bed height Our goal is to determine the size of the system and thus the first time to significantly reduce the outlay for such a system.

Since in the known moving bed reactor plants the automati Automatic or semi-automatic refill of the storage bunker above the adjacent bulk beds z. B. over chains trough conveyor and openable and closable storage bunker hatches takes place, a further object of the invention is that Effort for distributing bulk goods to the individual Reduce bulk beds. It is also desirable that Abrasion wear that the bulk material in the known bulk well-distributed facilities suffer, decrease, generally So to protect the fresh bulk goods better.

Finally, another object of the invention is the fluid treatment options in one and the same Be to expand the level of action, especially a simplified one Possibility to create the fluid on bulk materials different treatment properties when used to treat one and the same bulk layer, such as. B. on the one hand by adsorption and on the other hand on the Ways of chemical implementation, like this for bulk goods schungen z. B. from activated carbon or activated coke on the one hand and Calcium hydroxide on the other hand is known. For example, the flight  Electricity process in which bulk goods are finely ground. In the present case, however, both bulk goods are due to the Use as granules in a flowing bed used with a preferred grain size above 1 mm.

The method is used to solve the problem mentioned at the beginning with the features of claim 1, the charging device with the features of claim 8 and / or gas treatment Plants proposed with the features of claim 10.

Accordingly, the invention is based on the basic idea, one Bulk feed hopper inside or outside the reak tors to use in a charging position with bulk well loaded and on the various bulk beds Bulk bulk quantity delivery is proceeded. This can be particularly the case special so that the bulk feed container with at least one loading opening and at least one ver lockable discharge opening is provided and after loading load with bulk goods from the charging position via first bed is moved. There is at least one discharge released and it is discharged until the underneath the bulk material bed its target height of bulk well after, before or at the same time a bulk quantity has been deducted from the bottom of the bed is. Then the at least one discharge opening is ver closed and the bulk feed container to another Bed or in another loading position of the same bed proceed. After that, the process of bed after filling again at the next bulk bed to fetch. The bulk goods container returns to its later Charge position back to reload with bulk goods to become.

A bulk feed container according to the invention is expedient Usually as wide as the width of the bulk bed across to the direction of travel of the bulk material feed container. In the  Length of the bulk feed container seen in the direction of travel can be as large as the length of one or more of the after filling bulk beds, but also shorter, e.g. B. half way be long or even shorter. It is also possible to Bulk feed container with a plurality of over its Lockable discharge openings distributed to the floor area Mistake. But it is also possible to in the discharge openings to arrange a single row next to each other or one to use elongated gap as a discharge opening, in particular with the bulk goods container during unloading to proceed along the direction of travel or to stop only briefly in different positions, so that the bulk refilling gradually, from one bulk edge of the bed beginning to the opposite bulk edge of the bed is done successively. Through the open ent In any case, loading openings can only take out bulk goods emerge from the bulk material feed container until it is clear the discharge opening of the Bulk feed container has reached and thereby the Nach flow of bulk material stops. If the bulk feed container ter during the bulk quantity addition to a certain Bulk goods bed moved continuously or batchwise topographies that are particularly desirable of the bulk material bed surface can be achieved. In particular can have a ripple with relatively few discharge openings comparatively low amplitude than bulk bed top surface contour can be achieved and the bulk material container can be designed accordingly simple.

Just like the bulk beds by following the procedure below open bulk feed container along the bulk bed be filled with a partial bulk quantity can, it is possible to use the bulk feed container at least one charging container with a linear shape formed charging opening by the charging leg  container and / or the bulk feed container relative to each other be moved.

You can also use several charging containers with linear Charge opening are used, which differ Lichen bulk goods are filled, for. B. one with one Adsorbent and another with a chemical reac agent. If the charging containers are relative one after the other be moved to the bulk material feed container while doing so a different layer of bulk material in the bulk material dispensing container, becomes the bulk container thus with approximately parallel, in particular plane-parallel Layers of various fluid treatment agents filled. The The same can be achieved if the bulk material feed container when it is filled under a shared supply bunker with side by side outlet openings moves. Then plane-parallel layers of different Granules are generated one above the other. The layer thickness is determined by the vertical distance between the storage bunkers outlet openings determined. When replacing bulk goods the amount of bulk material is controlled accordingly both one and the other bulk goods at least one thin layer each in the respective bulk transferred good bed. This makes it possible to work in layers to realize built-up bulk beds within which Different gas treatment processes take place simultaneously the, such as B. Adsorption processes and chemical conversion processes. There can also be several with different Bulk material feed containers filled with fluid treatment agents are moved one after the other over the bulk material beds to achieve the same layer effect. Or the same bulk Gutaufbehälder is successively with each other Filled with fluid treatment agents and over the same bulk emptied good beds. A layer of bulk material can also be used Mixture of different granules.  

It is clear from the foregoing that a "fluid treatment "in the sense of the invention, inter alia, a chemical treatment lung, an adsorptive cleaning treatment, but also a May be heat treatment or a dust removal treatment. Heat treatments can e.g. B. by entering heat energy sources or by heat generation by chemical Reaction can be realized. Gas dedusting occurs e.g. B. in that dust particles on the bulk material attach the kel surfaces and with the bulk material from the Bulk material bed are discharged.

A gas treatment plant according to the invention for performing the method described above has a hori zontal charging channel on the above the bulk beds is arranged and connects them so that the Bulk feed container through the charging channel between a batching position and the bulk feed items is movable above the beds. Such charging channel can be arranged above bulk material distribution floors be located above each bulk bed. This can be arranged outside the reactor; it is preferably built under the reactor. He can fill or replace the storage bunkers. The after State-of-the-art storage bunkers for each Bulk bed can therefore above the bulk material distribution floors to form a common horizontal charging channel to get nabbed. This eliminates both the filling openings for the storage bunker as well as the material-wearing one Transport of the bulk material above the reactor ceiling as he does is known from the prior art cited at the beginning. It is also possible to completely dispense with bulk material distribution floors len and the gas collection spaces of neighboring bulk good beds together to form a horizontal charging channel summarize. This increases the overall height of the gas treatment system even more reduced. With such a Arrangement, the bulk goods container can perform the function of  Throttle or closing flaps take over which one Prevents treated gas from escaping from a bulk bed changes if the bulk material feed container is above the bulk bed and a refill of bulk goods tion is made. This throttles or prevents it Gas flow through the bulk bed in question, as in the Document WO 91/12069 is desired. However, they do not apply in the present invention, the throttle or Ab blocking organs whose function is the bulk goods container takes over.

The bulk material discharge below each bulk material bed can be done like described in the prior art mentioned above, about Funnel or to achieve a lower overall height using a Conveyor belt take place. It is particularly advantageous to everyone However, if below the bulk material discharge openings Discharge floors of the individual bulk beds a horizon taler disposal channel is provided, through which a for all connected bulk material beds effective longitudinal conveyor is movable for bulk goods transport. This can be a Conveyor belt. However, it is particularly advantageous to provide a bulk receptacle that - how the bulk goods container - across the entire bed width extends and can be moved in the longitudinal direction of the bed. Ver In terms of driving technology, it is particularly favorable if both the Bulk feed container as well as the bulk goods receptacle containers above and below the same bulk material position the bed. If then bulk discharge directions of the relevant bulk bed opened or operated, the withdrawn bulk material immediately falls into the bulk goods container and on top of the bulk goods bed fresh bulk material flows from the bulk material from above feed container after. This ensures that always the full bed height is maintained.  

In all cases where there is a common disposal channel is provided below the adjacent bulk beds, is only a single bulk discharge point for the whole Gas treatment plant or a strand of neighboring Bulk beds are required, so that comparatively less Measures to prevent gas leakage are required. For the disposal channel - as well as for charging channel - again two possible configurations: In one arrangement, the disposal channel is in place of bulk material discharge funnels below the closed Gas distribution room provided. In the other case, the Disposal channel arranged higher, namely within the Gas distribution rooms of the adjacent bulk containers, which too for this purpose with the omission of side partitions be connected to each other to form the disposal channel. Here the system height is further reduced and the Bulk goods container the function of throttle or Shut off means by opening the gas inlets to the gas distribution room below the bulk bed under the the bulk container is straight, ver closes or at least narrows in cross-section, so that Zei only partial quantities of the bulk goods exchange gas to be treated or no gas at all in the bulk material partially exchanged bulk bed can flow.

The charging positions can also move at both ends Range be provided around the stream of gas to be treated as little as possible. It is conceivable in the charging position also ver the bulk feed container tical to move to another floor, z. B. in a circle run over two levels.

The aforementioned, as well as the claimed and in the Aus described leadership examples to ver according to the invention process steps and components are subject with regard to their process conditions, their size, shape  design, choice of materials and technical conception kei NEN special exceptions, so that the respective current application area known selection criteria limited application.

In Fig. 1a, a pipe duct 1 can be seen , at the right end there is a charging station 2 and a gas inlet nozzle 3 and at the left end there is a gas outlet nozzle 4 through which the fluid treatment system 10 located inside the Rohrka channel 1 with the fluid to be treated is applied or disposed of. The pipe channel 1 can thus connect upstream or downstream reactors in the fluid path, e.g. B. on the inlet side of a thermal reactor, such as a heat treatment plant and on the other hand, a downstream fluid treatment / cleaning stage or an exhaust gas fireplace. Depending on the available space, the pipe duct 1 can also have at least one fluid deflection point, so that the gas inlet connector and gas outlet connector can be arranged relatively close to one another. It can also be designed horizontally as well as vertically mean, as well as multi-layered, i.e. have several fluid deflection or distribution points in order to do justice to the available space. So relatively large filter areas, ie for treatment systems for extremely large fluid flow rates can be realized in a convenient manner.

The tube channel 1 is equipped in its interior with a plurality of moving bed reactor modules 5 arranged next to one another in the direction of the tube channel axis, which are only separated from one another by metal partition walls which extend transversely to the reactor channel axis. Such moving bed reactor modules 5 are shown by way of example in FIGS . 6a to 6c and will be explained in more detail in this context.

At this point it should be mentioned that the moving bed reactor modules consist of the following components: a bulk material bed 18 , made of a particulate bulk material, e.g. B. an activated carbon, a catalyst, calcium hydroxide and / or other. The bulk bed has one of Seitenwän covered, z. B. square base and the treatment process adapted bed height of z. B. 1.2 m. It rests on a so-called inflow base 6 , which preferably is the one from European Patent No. 0 257 653 B1 has known design, that is to say it consists of at least side by side arranged first bulk material discharge funnels 6 A or funnel-shaped bulk material discharge channels. Their side walls have through openings 6 B. Above the same are roof-shaped distribution elements which protrude from the funnel walls 6 A towards the funnel interior and allow the bulk material to pass downwards and the fluid to enter the bulk material bed upwards. A wide rer fluid inlet gap forms at the mouth of the second bulk material discharge funnel 6 D, which adjoin the outlet opening from the first bulk material discharge funnel 6 A with a circumferential gap downwards. Down to the second bulk material discharge funnel 6 D subsequent bulk outlet pipes 6 E, which can be made telescopic for thermal and mechanical reasons, penetrate a dust cover 6 F in the form of a cross-sectional bottom. This bottom 6 F, the bulk material discharge funnel 6 A / D 6, as well as the outer peripheral walls enclose a fluid distribution chamber 6 G below the bulk material bed 18th In addition to a side wall of the fluid distribution space 6 G, the lateral inflow channel 21 B extends inside the pipe channel 1 parallel to its longitudinal axis and guides the fluid to be treated along the entire pipe channel 1 . Since all Fluidver subspaces 6 G by a Anströmfenster 6 H in the partition wall to the immediately adjacent inlet channel 21 B are provided, each moving-bed reactor module of the tube channel to be acted upon uniformly with fluid to be treated, wherein to make sure of reaching flow cross-sections, that the pressure loss in all the bulk material beds so well as is the same size.

Below the dust cover 6 F under each Schüttgutauslaßrohr 6 E a clocked horizontally movable Schüttgutaustrags device 6 I arranged. Their structure can be big in itself, e.g. B. as described in more detail in EP 0 357 653 B1.

Above each bulk material layer 18 there is a gas collecting space 7 , with a side outflow window 7 A for fluidic connection with an outflow channel 29 B for treated fluid. This extends along the full length of the pipe channel 1 .

As can be seen from Fig. 3 in more detail, a bulk feed container 12 is provided, which can be moved along guides 22 A by means of a simple trolley 30 in the interior of the pipe channel parallel to the pipe channel axis. In the illustrated embodiment, the bulk feed container 12 has the same cross section as each moving bed gate module 5 . So that the bulk material feed container 12 between the charging station 2's and all of the bulk material beds 18 to be supplied by him can be moved, all affected moving bed reactor modules are connected by a Chargierka channel 15 parallel to the pipe channel axis. See especially Figures 6a and 6b.

The bulk feed container 12 will be explained in more detail with reference to FIGS. 3 to 6a: It consists of a flat trough with a plurality of lockable discharge openings 14 in the form of mouth openings of bulk material funnels arranged with bulk material discharge tubes 12 A. In this respect, the bottom corresponds to that flat tub, ie the bulk feed container 12 of the type and arrangement of a bulk material distribution floor, which he arranged as a stationary bulk material distribution device between a bulk material storage bunker and the bulk bed underneath and is already known from EP 0 357 653 B1. The difference between the known is that this bulk material distribution floor has a frame with a chassis and is thus designed as a movable carriage. Below the outlet mouths of the bulk material outlet tubes 12 A, a continuous over the entire cross-section of baffle plate is located 12 B with the arrangement of the bulk material outlet pipes 12 A corresponding distribution and size of bulk material through laßöffnungen 12 C. In the perspective view of Fig. 6a is a front wall and part of the Dust plates of the movable bulk feed container 12 have been omitted for the sake of clarity.

A special feature of the bulk material container 12 consists of a, possibly additional, side wall, the medium as a throttle 27 (Fig. 4a / 4b) 7 A is used for closing the Abströmfensters. This mitbe away from the bulk feed container 12 plate prevents that in the area in which the bulk feed container 12 is located, treated fluid from the gas collection chamber 7 can pass into the continuous outflow channel 29 B. Characterized independent shut-off or throttle valves for each of these Abströmfen most 7 A are dispensable.

The functioning of the bulk material feed container 12 is such that it is loaded with bulk material in the charging position 23 shown in FIG. 1a and is then moved in each case over the bulk material bed 18 which requires a partial exchange of bulk material. Except when bulk goods are exchanged, the discharge device, such as the 12 B jam, remains closed. The charging process taking place in the charging station 23 can take place in various ways. In the embodiment shown in Fig. 1a, a storage bunker 2 A for bulk material with a lockable bulk material discharge floor 2 B is provided. The movable bulk material container 12 is filled with fresh bulk material from the storage hopper 2 A by the latter.

Alternatively, the charging process can be carried out in the manner shown in FIG. 5. Here, the storage bunker 2 A has at least one, in the exemplary embodiment there are three, bulk material outlet slots and the storage bunker and bulk material feed container can be moved relative to one another in the direction of the pipe channel axis. This allows a bulk layer to be filled from one end to the other of the bulk feed container (in the direction of travel). In the Darge presented embodiment, the storage hopper 2 A in part bunker 2 A '2 A "and 2 A' divided ''. Each may be filled with a different bulk material. The off supporting slits different lie deep, so that bulk material layers 18 A ' , 18 A ", 18 A '''are formed in the movable bulk feed container 12 .

The bulk material exchange takes place in a manner known per se, namely by moving the bulk material discharge device 6 I ( FIG. 4a) horizontally with the release of the bulk material pipe mouths, while above the bulk material bed 18 the bulk material feed container 12 with open bulk material outlet pipes 12 A is stationed. The bulk material sags automatically according to the actuation of the bulk material discharge device 6 I from top to bottom, so that fresh bulk material automatically follows above.

The bulk material discharged can be removed as desired. Preferably, a movable bulk receptacle 20 is used, which can basically be identical to the bulk feed container 12 . Such an example was used in the figures. A trained in the Rohrka channel 1 through disposal channel 19 ge equips one of the adjacent moving bed reactor modules via the step-by-step method of the bulk material receptacle 20 . This is emptied in the bulk position 26 shown in FIG. 1a.

Another special feature of the movable bulk material receptacle 20 is a side wall designed as a throttling means 28 which (as with the bulk material feed container 12 ) is moved along and blocks or blocks the fluid passage through the respective inflow window 6 H of the moving bed reactor module under which the bulk material receptacle 20 is located throttles. This prevents separate adjustment flaps.

A thermally particularly advantageous alternative for the arrangement of the inflow and outflow channels to and from the wall-mounted reactor modules along the pipe channel 1 is shown in Fig. 2a. Here the lateral inflow and outflow channels 21 B, 29 B, which can now turn out to be smaller in cross section, an upper outflow channel 29 A and a lower inflow channel 21 A were added. These are fluidly connected to each other over their entire length, so that the essential part of the inflowing, ie to be treated fluid can flow below the inflow floor and the essential part of the outflowing, ie treated fluid above the bulk material beds. The reactor floor and reactor ceiling, ie the pipe channel floor and the pipe channel ceiling are thus heated and replace the usual trace heating.

The fluid treatment system according to the invention allows economical fluid treatment, especially for extremely large amounts of fluid, such as a few hundred thousand or million m ^{3 of} gas per hour.

A particularly advantageous fluid treatment process (An Proverb 18) is the bulk beds as a filter for a first fine particle distributed in the fluid stream Bulk or dust to use. There are e.g. B. Procedure for treatment, especially for cleaning fluids, ins special of gases, with at least a first bulk material known in which the first bulk material in a fluid stream is distributed and from this to a dust filter torn and retained there on a filter surface, while the fluid flows through the dust filter. An invented fluid treatment system according to the invention is now for such a Ges entrained current / filter method proposed, being as Dust filter on a bulk bed as filter surface Transmitter moving bed reactor is used, in which the fluid flows through a bulk bed from bottom to top and on second bulk material forming the bulk bed in countercurrent the fluid through the moving bed reactor from top to bottom wanders. At the lower end of the bulk material bed there are piles sub-quantities subtracted and at the upper end of the bulk bed tes given up on the second bulk material, d. H. the Bulk material of the bulk material bed, and in the intermediate grain volume between its bulk particles and / or dust or that first bulk material or a fraction thereof from the fluid stream settles and together with the bulk to be discharged Good quantities deducted at the lower end of the bulk material bed will become. In particular, treat the second bulk material  Particle of the bulk material bed also the fluid. - This one Of course, the method can also be used advantageously zen if the filling of the moving bed reactor via statio nary storage bunker and not on the ver according to the invention mobile bulk feed container.

This process opens up a completely new dimension sion of entrained flow / filtration technology, both for pure gas dedusting as well as for targeted loading treatment of gases with finely ground bulk materials in the Entrained current. In both cases there is the problem that a so-called filter cake on the filter surface forms that grows constantly. On the one hand, this increases the pressure loss gradually and on the other hand also increases Residence time of the gas to be filtered in the filter cake. Because after a certain time the pressure loss in the filter box Chen is too large, this must be removed and then new being constructed. This is complex and leads to incon inaccuracies in fluid treatment. Both will be problems by the inventive, trained as a moving bed reactor Dete bulk filter avoided because the dust or parti kel from the entering fluid in the entrance zone of the Place the bed of bulk goods, i.e. where bulk goods continue animal or quasi continuously from the moving bed reactor is subtracted. With this bulk quantity deduction also trapped dust and / or other particles carried out. This almost keeps the filtration performance completely constant, so the inconsistencies mentioned above be avoided. So here is a quasi continuous Lich self-cleaning, the filter cake thickness is constant holding filter realized, which practically never cleaned must become.

Another advantage of this method is that the (second) bulk material particles of the moving bed reactor are available for further fluid negotiation steps. So z. B. the fluid flow to be treated with the formation of an entrained flow first bulk material staubför shaped activated carbon, with which an adsorptive gas cleaning is carried out, this partly taking place in the entrained flow phase and partly when this dust is captured in the moving bed reactor . The depth of the dust can be influenced by appropriate control of the bulk material exchange. The (second) bulk material particles of the moving bed reactor can then, for. B. also consist of adsorbents, such as calcium hydroxide, NaOH or another material suitable for the treatment of the fluid for the chemical treatment of inorganic pollutants, such as HCl, SO _2, etc.

Bulk materials for the moving bed reactors include rem a granulate of brown coal, hard coal, limestone and / or Sorbalit in question, which in turn also in layers Bulk material bed can be present, which is the bulk material transport trolley (bulk container).

It also goes without saying that this is from the moving bed trail bulk modules discharged, also by type of bulk goods carried out separately and can also be reused, in case its fluid handling capacity is not yet full has exhausted.
